I had posted a while back looking for advice on moving my service entrance out to my garage. I'm finally getting down to business, and have permit in hand, but I do have a couple of questions remaining.

I currently have aerial 100A service over my garage, feeding the back of the house. My plan is to install a new meter and a new 100A panel at rear of garage, then feed the house as a subpanel. I'll be using a 100A breaker and 1/0 AL run through the garage rafters, then in 2" conduit trenched to the house.

The last time I trenched power to garage in my last residence, I ran a data-cabling conduit next to it. Permit issuing officer said he's never heard of a 12" required separation distance, but that's what I'm reading is required in code. Can anyone substantiate that?

Do the phone company and cable company typically supply their own interface boxes? Hard to get any information on that.

Alberta seems to have their own rules for service masts. I believe the one at my house is just 2" NPS galvanized pipe, but I'm seeing 1-1/4" RMC and 2" RMC are used here. This is not the same as regular conduit, I'm assuming.

Grounding would be done at the entrance panel, but putting 2 ground rods in near the service drop is going to be difficult (concrete driveway) and permit officer suggested ground rods in the trench at the front of the garage. Seems ok to me, though it would be 10m of #6 wire just to get to them. Any issues that anyone can see with this?
